OK looks like most of the "input" side has been looked at...would anyone else who has had a cat converter collapse be able to gauge their symptoms to the ones presented here?

The symptoms you are now describing are different to what was originally described. Is this so?

Full and complete answers will help us to help you. Re-read all the above posts and try to fill in as many answers as you can.

Is there any check engine light on, or has there been since you have had it? Have you had the ECU scanned for any stored codes, if so could you give us the numbers of the codes, will be in the form of P0*** or P1*** with the last three digits * being 0-9 (not anyone's "interpretation" of what they are please as this can be confusing/lost in translation).

I strongly think you have a simpler problem than you thought being that you say it starts slow and the cranking speeds up before engine fires. This tells me you have a starting system issue. Starting system is composed of the starter, engine ground, starter power wire (B+), and starter relay. Relay is in the fuse box in the engine compartment. I'd ensure the ground is good to the engine first. take some jumper cables and put black on bat negative (-) and the other black jumper on the engine itself, like a clean bolt somewhere of the tow loop they put on.. make sure the clamp bites through the paint if it has any to reach metal. Make sure the cables won't get caught in the fan or belts and try starting it up. If the cranking has become normal like, then it's a sure thing that your engine ground is poor (like me lol). If nothing changes though, then It could likely be a corroded starter power wire or bad starter, but I doubt the starter's bad. A starter with a bad connection be it pos or neg will start off slow and pick up momentum like you describe. I kinda and hoping and suspecting the ground though cause of your high idle issue.. sensors don't function well with improper grounds. goodluck
I don't know about your idle other than the notorious oxidation issue on the tps/maf/iac connectors. clean them, wiggle them, whatever. and see if the idle gets under control. Mine will stay at 1200 till I come to a stop, then it will finally drop to like 900. if i roll again, the idle goes back up.

Ok , it drives good EXCEPT for when I come to a stop, the idle revs up to about 3000 and then slowly goes down. It does this everytime I come to a stop. Any idea of what that may be? I got a new to me TPS, and I am going to clean the mass air flow and the idle/air control.
If you know what else it may be, please steer me in the right direction.


Try cleaning all the electrical connectors on the engine, Idle Control, TPS, MAF, and etc., it is a common problem on Sportages that the connectors get dirty and cause all sorts of problems.

What is the best way to clean the connectors? I have tried 70% alcohol for the maf. But I bought some spray cleaner for it also. Will it work on the idle/air control too? Do I spray it into the holes and on the connections?

I has the same problem on my harley and it was poor seals on the intake manifold. My old cj-7 did the same thing. Sometimes the idle would stay real high, drop down sometimes or drop so low it would stall. The carb gasket and vacuum lines were to blame. try spraying carb cleaner around the intake and see if there is a leak anywhere. Be generous with the cleaner and see if idle changes, then narrow it down to exactly where the leak is.

The first time we tried to video it, the battery cables started smoking, The ground was very hot to the touch, tha positive was warm but not too hot. I beat on the cables and then tried it again and this time we got the video. I think I need a new ground wire or something.

I hadn't seen the video before my last post. The starter seems slow. If you jump it with another battery, does it turn faster? Also, my s-10 had a problem with the bogging like that. It was the fuel pump. It would idle from the vacuum supplying fuel, but would bog when the gas was pressed. Then the idle would go up from the gas that was just vacuumed up.The problem we had is we actually heard the pump running, but the fuel line was broken inside the tank. When you turn the key on, do you hear the fuel pump running? If it is bad, turning the engine for 20-30 seconds will vacuum fuel to the engine then run off of that. It would also explain your idle going up and down. Also, pull your fuel line at the engine and turn the key on and be sure you are getting good gas flow.

it doesnt turn over any faster with another battery hooked up, I am wondering if it has been my ground wire all along. I think I will change that next and see what happens.
